Study Notes
- Vertebrates and Invertebrates: Animals with backbones (vertebra) are called vertebrates, while animals without backbones are called invertebrates.
- Vertebrates: Includes animals like amphibians, reptiles, fish, mammals, and birds.
- Amphibians: Cold-blooded animals, change body temperature based on surroundings, breathe through gills as babies, then develop lungs as adults, reproduce by laying eggs in water, have moist, permeable skin.
- Reptiles: Have rough, scaly, dry skin to prevent water loss, lay eggs on land, breathe through lungs, examples include chameleons, crocodiles, alligators, turtles, snakes.
- Fish: Adapted to fresh and salt water environments, covered in scales that can be slimy or rough, breathe through gills, some lay eggs in water while others are live bearers, examples include goldfish, mudfish, sharks, and eels.
- Mammals: Warm-blooded animals, give birth to live young, have mammary glands to produce milk, examples include humans.
- Amphibians: Examples are frogs, toads, salamanders, have gills as babies, then develop lungs as adults, reproduce by laying eggs in water, have moist skin that can absorb water, breathe through gills as young, then lungs as adults.
- Reptiles: Examples are chameleons, crocodiles, alligators, turtles, snakes, have dry, scaly skin, lay eggs on land, have different types such as those that live on land and those that live in water, breathe through lungs.
- Fish: Examples are goldfish, mudfish, sharks, eels, have gills to breathe, can live in fresh or salt water, some lay eggs in water while others give birth to live young.
- Mammals: Examples are humans, give birth to live young, have mammary glands to produce milk, are warm-blooded, have a temperature range between 37-38 degrees Celsius.- The text discusses different groups of animals based on their characteristics and development methods.
- Mammals are a group of animals that have hair or fur, develop their young inside the mother's womb, and include examples like humans, dolphins, bats, and lions.
- Placental mammals have a fully developed embryo inside the mother's womb before birth.
- Marsupial mammals, on the other hand, have young that are born before they are fully developed and stay in their mother's pouch for further development.
- Monotreme mammals lay eggs and include examples like the platypus.
- Vertebrates are a larger group of animals that have a backbone, and are further divided into groups like mammals and invertebrates.
- Invertebrates, which do not have a backbone, include groups like sponges, echinoderms, mollusks, and worms.
- Sponges are simple animals with a symmetrical body and no tissues or organs, and are often used as an example in cartoons like SpongeBob SquarePants.
- Echinoderms are spiny-skinned animals with radial symmetry and an endoskeleton, and include examples like starfish and sea urchins.
- Cnidarians, a type of invertebrate, are soft-bodied animals that can use tentacles for locomotion and have stinging cells.
- Mollusks are soft-bodied animals that can be enclosed in shells for protection and include examples like snails, squids, and clams.
- Worms are another type of invertebrate and can be classified as round, segmented, or flatworms.
- Arthropods, a large group of invertebrates, have a hard outer skeleton called an exoskeleton and include examples like insects, crustaceans, and arachnids.
